EFFECT ON PROCESS PARAMETER OF FDM MACHINE USING MADM METHOD

Mechanical Engineering

There are several different methods of 3D printing, but the most widely used is a process known as Fused Deposition Modeling (FDM). FDM printers use a thermoplastic filament, which is heated to its melting point and then extruded, layer by layer, to create a three dimensional object .Fused deposition modeling (FDM) is a fast growing rapid prototyping (RP) technology due to its ability to build functional parts having complex geometrical shapes in reasonable build time. The dimensional accuracy, surface roughness, mechanical strength and above all functionality of built parts are dependent on many process variables and their settings. Rapid Prototyping (RP) technology has been advanced to fabricate initial prototypes from various materials. Stratasys Fused Deposition Modeling (FDM)is one of the typical RP processes that provide functional prototypes of PLA, ABS, nylon, wax etc plastic material. Rapid prototyping technologies for easy production of prototypes, parts and tools are new methods which are developing unbelievably quickly. Successful product development means developing a product of high quality, at lowest cost, in the shortest time, in at a reasonable price. The development of the part and its introduction to market is time consumption process. But ’time is Money’ and therefore could be said that money saving is greatest when time to market is minimalized utmost. Experimentation was planned as per taguchi’s L9 orthogonal array .In this techniques are using such as, multi objective optimization on the basis of ratio analysis(MOORA),Analytical hierachy process(AHP) method for optimization of fused deposition modeling(FDM)
